RCBS Full Length Small Base with Roll Crimp 2-Die Set - 308 Winchester

This two-die set is for bottleneck type cases used in tight-chambering semi-automatic, pump or lever-action rifles. It consists of a Small Base Sizer and Seater Die has a built-in roll crimper to secure the bullet at the same time it’s seated.. The sizer resizes cases below SAAMI minimums, reducing the shoulder and body by a few thousandths. It also de-primes the case. To seat bullets without crimping, simply unscrew the die until the crimp ring no longer engages the case mouth.
